' STORAGE-BATTERY PLATE.

To all whom it may concern:

Be it known that I, ALFRED O. TATE, a sub 'ect of the King of Great Britain, residing in t e city of Toronto, county of York, Province of Ontario, Dominion of Canada, have made a new and useful Invention in Storage- Battery Plates, of which the following is a specification. a

My invention is directed to an improvement in storage battery plates in which the active material, such as lead oXid, is applied directly to conducting plates, grids, or the like, and known in the art'generally as of the Faure type, and particularly to an improvement upon a specific storage battery plate disclosed in a prior application filed by me in the U. S. Patent Office on the 1st day of December, 1905, hearing Serial No.', 289,796, and it has for its objects, first, to materially lighten the entire structure of the plate disclosed in the before-mentioned application; second, to aflo'rd a means for more eflectually retaining the active plate.

The structural plate disclosed in the be fore-mentioned application is of a bifunctional nature and embodies. interleaved anodes and cathodes of good 0 nducting material, preferably lead, grooved on their opposite faces so as to constitute flanges, in which grooves the active material, such as oXid of lead, is located, and thin stri s of porous insulating material are locate between the interleaved grooved strips or ribons.

In the present improvement I have reversed the arrangement in respect to the of the parts, in that I have grooved the opposite faces of the porous insulatin strips so as to constitute chambers or cavities forthe active material, and have located the interleaved anodes and cathodes on op osite faces, all of the parts being bound toget er in same manner as disclosed in the before-mentioned 'ap lication. 'Viith such a structure as dis'closecF herein I am enabled to materially lighten the I may rovide strip or ribbon li e anodes and cathod es of a very thin structural nature, and may also efiectually increase the effivcie'ncy of the plate, in that the active matelate, for that rial is more securely or firmly held in the grooves 1n the opposite faces of the porous non-conducting strips.

My improvement will be fully understood material in place in the.

Specification of Letters Patent. Application filed October 29.1907. Serial No. 399.641.

by referring to the accompanying drawings, in which Figure 1 represents a side elevational view of one of my novel bifunctional storage bat tery plates showing the parts separated in the central part thereof, so as to better understand the manner of effectually binding all of the same-together. Fig. 2 is an enlarged detail and vertical sectional view showing the interior structure, saidsection being taken on the line 2-2, Fig. 3, and as seen looking thereat from right to left in the direction of the arrows. through Fig. 2 on the line 33, showing the relation of the essential parts of a complete plate. Fig. 4 is a perspective view showing one of the spacing and locking blocks and the manner in which they are strung upon one of the conducting rods which constitute the poles of the plate. Fig. 5 is Patented Feb. 25, 1908. i

Fig. 3 is a sectional view taken or holding a transverse sectional view of one of the grooved porous strips for supporting the active material, said view being taken on the line 55 Fig. 6; and Fig. 6 is a vertical sectional view of the lower end of one of said strips, the same being taken on the line 66 Fig.5. These Figs. 5 and 6 are made upon an exaggerated scale for the purpose of more clearly illustrating the parts.

Referring now to the drawings in detail, in

all of which like letters of reference" represent like parts wherever used, a and 0 represent respectively the anode and cathode strips of a" complete bifunctional plate, said parts in the present instance being composed of thin narrow strips of any good conduct-- ing material, especially adapted for use in storage batteries and each enlarged at one end and provided'with a hole or opening therethrough adapting it to-be strung upon the proper one of the two conducting bars or rods 2;, o, the upper of said bars sustaining all of the anodes u and the lower one all of the cathodes c. ferfroin those disclosed in the before-mentioned application to the extent that they are not grooved on their opposite faces, but

are simply thin flat strips, as clearly indicated in Figs. 2, 3 and 4 d, d, are hard rubber or equivalent binding blocks for holding the entire plate together by end-pressure, and i, i are insulating spacing blocks, said blocks d, (Z and. i, 2' having cylindrical holes adapting them to be strung upon the bars or rods '0, v with the anode and of the drawings.

These anodes and cathodes difshown in Figs. 5 and 6 of the dr-awings, said grooves being inclosed at their lower ends and the arrangement such that the active. material Z, such as is ordinarily used in storage batteries of the Faure type, is secured in place in the opposite grooved faces thereof.

. e, c, e, e, are screw-threads upon theends of the conducting bars or rods '0', 'v, and f, f, f, f, are nuts for binding thepart's together, act-- ing also as binding terminals.

h, h are sheets of soft rubber or equivalent yielding material which act as cushions and compensate for any expansion or contractio of the completed plate when in use.

All of the parts disclosed-in the present application are identically the same in structure and in function as the corresponding parts disclosed in the before-mentioned application, except that in this case .theactive material Z,,Z is held inthe, grooves in the faces of the porous strips g, 9, while the anodes and cathodes are fiat conducting strips or ribbons adapted to cover the entire space between the adjacent faces of said porous strips, so that when'all of the parts are secured together by the conducting bars or rods '1), 'v and nuts f, f with the spacing and locking blocks "i, t in position, the mode of operation will not be substantially different from that disclosed in the before-mentioned application. But, by reason of the fact that the anodeand cathode strips or ribbons a, a and c, c, which are preferably of metal, may be much lighter and because of the fact that the active material is held in the faces of the porous non-conducting stripsg, 9, improved results are necessarily obtained, it being apparent that the lateral, faces of the entire plate are practically plane surfaces of large porous 'area which will readily admit the electrolyte to all parts of the active material, and the structural relation is such that said active material will not be released under any conditions of usage.

I do not limit my invention to the specific structural arrangement of parts disclosed. in

'. the present application, as I believe in 'invention is generic as to a bifunctional sterage' battery plate offtho Faure type composed of interleaved or interrelated nodes and cathodes of strip or ribbon like form, and inter-' mediate porous insulating media provided with chambers ,or cavities-adapted to mechan ically support active material-against the ing strips, substantially as 6. A bifunctional storage battery plate, 125

faces of the anodes and cathodes, said. anodes being connected together at one end to a common conductor and the cathodes similarly connected at the other end, and the entire arrangement such that the active material will be entirely inclosed and held in place by virtue of the structure of the porous media. a

' Having thus described my invention what I claim and desire to secure by Letters Patent of the United States -is- 1. bifunctional storage battery plate,- embracing. interleaved anode and cathode strips or ribbons, and intermediate porous insulating media provided with chambers or cavities adapted to mechanically sustain or support active material Within said cavities 1 and against the faces of said strips or ribbons;
